[PATCH 1/3] sched/fair: Remove unused sched_fair_runnable()

The last caller of sched_fair_runnable() was removed by commit
50653216e4ff ("sched: Add support to pick functions to take rf").  Its
siblings sched_dl_runnable() and sched_rt_runnable() are still used, but
the fair variant is now dead.

As a static inline it does not trigger -Wunused-function, so it has gone
unnoticed.  Remove it.  No functional change.
